Abstract

Casting is a manufacturing process that uses molten metal and molds to obtain a product that is closer to its final geometry. The quality of casting products is influenced by several factors and one of the important factors is the mold. The sand that is often used in making molds is resin coated sand, since this sand will bond to one another if it is heated. The research focus is determine the effects of grain size and heating temperature of resin coated sand on the mechanical properties of the mold which include compressive, shear and tensile strength. This study used an experimental method with large parameters of resin coated sand and heating temperature. From the test results, the highest compressive, shear and tensile strength values are Produced by sand with grain size less than 300 µm are identified.. The high heating temperature makes the bonds between the sands stronger and the strength value is higher..

Abstract

An excavator is heavy equipment with a hydraulic system as the main drive and along with its uses, many parties have developed it as a means of production and as a means of learning. The education world needs excavators as learning tools and practice media are currently constrained by price when commercial units are used. Therefore, a learning media that is more compact but does not abandon the main essence of learning is needed. This research aims to analyze the front attachment design of the Zhugimada mini excavator using the finite element method. The research was carried out using the ANSYS application for the static load simulation process and testing was carried out with a bucket containing sand weighing 25 kg and using three hydraulic cylinders. The simulation results show that the maximum von Mises stress value in the bucket component is 43.226 MPa and the maximum deformation is 0,51285 mm in the tooth bucket so in general the design of the Zhugimada mini excavator front attachment components can be declared safe and can be continued in the fabrication process.
